So i am buildig a guitar, equipped with a kahler tremolo, and i despise locking nut mechanisms. I just got some gotoh locking tuners, excellent hardware by the way, and the roller nut seems pretty awesome, technically speaking, my strings would never go out of tune with the roller to roller setup of the kahler and the nut. How do you adjust the roller nut for action? Ive made hundreds of bone nuts, and the ones i buy premade ALWAYS need to be lowered/highered/remade after a refret-job. anyone got any ideas?
